Pituitary adenomas are slow-growing, noncancerous tumors of the pituitary gland—the master gland controlling various hormones in the body. Their symptoms, causes, and modern treatment options have evolved significantly, especially with access to technologies like CyberKnife. Explore a complete guide to pituitary adenoma treatment and learn why Valentis Cancer Hospital stands out for advance cyberknife treatment in India.
What is a Pituitary Adenoma?
A pituitary adenoma is a benign tumor on the pituitary gland. While not cancerous, its impact can be serious due to hormone imbalances or pressure on surrounding tissues. Common types include non-functioning adenomas (without hormone production) and functioning adenomas (with excess hormones such as prolactin, growth hormone, or ACTH).
Symptoms of Pituitary Adenomas
Symptoms depend on tumor type, size, and effects on hormone production or nearby structures:
- Persistent headaches
- Visual disturbances (blurry vision, visual field loss)
- Fatigue and weakness
- Hormone imbalances—menstrual changes, infertility, weight changes, sexual dysfunction
- Nausea and vomiting (with adrenal insufficiency)
- Unexpected mood changes or depression
- Excessive thirst and urination (rare, linked to diabetes insipidus)
- Symptoms of hormone hypersecretion, like acromegaly or Cushing’s disease
Many pituitary adenomas are discovered incidentally during imaging for unrelated reasons, especially when small and asymptomatic.
Causes of Pituitary Adenomas
The underlying cause remains largely unknown, but some genetic syndromes, such as multiple endocrine neoplasia type 1 (MEN1), may increase risk. Most cases occur sporadically and are not inherited. Rarely, family history or mutations contribute.
Diagnosing Pituitary Adenoma
Diagnosis requires a detailed approach:
- Medical history and physical examination
- Hormone level testing (blood and urine)
- Imaging (MRI or CT scans) to assess tumor size and location
- Visual field tests for tumors affecting the optic nerves
A multidisciplinary team—endocrinologist, neurosurgeon, and radiologist—reviews findings for precise treatment planning.
Treatment Options for Pituitary Adenomas
Treatment depends on tumor size, hormone activity, patient health, and presence of symptoms.
Observation
Small, non-functioning, asymptomatic tumors may only require monitoring with periodic scans and hormone tests.
Medication
For functioning adenomas like prolactinomas, medications such as dopamine agonists shrink the tumor and restore normal hormone levels. Additional drugs can suppress excess hormones for other adenoma types.
Surgery
Minimally invasive endoscopic transnasal surgery (endonasal transsphenoidal resection) is the first-line treatment for most symptomatic or large adenomas. It relieves pressure, restores hormone balance, and corrects vision problems. Rarely, open craniotomy is needed.
Radiation Therapy
Radiation is a key option for tumors that are not fully removed surgically or are inoperable. Stereotactic radiosurgery, including the advance cyberknife treatment in India, provides precise, high-dose radiation targeting the tumor while sparing healthy tissues.

Pituitary Adenoma CyberKnife Treatment
CyberKnife S7 is a state-of-the-art form of stereotactic radiosurgery offering:
- Non-invasive, outpatient precision therapy
- Real-time tumor tracking and millimeter accuracy
- Lower risk to vision, brain structures, and hormone function compared to conventional radiotherapy
- Short procedure times and faster recovery
For pituitary adenomas near critical areas or with residual tumor, CyberKnife treatment is often preferred for its safety and effectiveness.
